Serial No. 264,109.

To @ZZ 1.071.071?, it '1n/ty concer-rt:

Be it known that 1, ALONZO H. LAY'roN, a citizen ol the United States,residing at llliance, in the county of ,loxbutte and @tate ot Nebraska,have invented a new and useful Lubricatingdourual, ot which thefollowing is a specilication.

This invention relates to jeurnal-bearings, more particularly to thebearings ot railwaycar axles, and has tor its object to provide asimply-constructed and easily-applied device whereby the bearing may becontinuously and automatically lubricated and the `lubricant suppliedonly so last as needed, thus insuring uniform application ot' thelubricant and prevent wasteful use ol the saine.

With these and other objects in view, which will appear as the natureot' the invention is better understood, the same consists in certainnovel features of contrilction, as hereinafter fully described andclaimed.

In the accoiniianying drawings, forming' a part oi this specilication,and in which corre spending parts are denoted by like designan ingcharacters, is illustrated the preferred form of embodiment oi theinvention capable of carrying the same into practical operation, itbeing understood that the invention is not necessarily limited thereto,as various changes in the shape, proportions, and general assemblage ofthe parts may be resorted to without departing from the principle of theinvention or sacrilicing any oiu its advantages.

ln the drawings, Figure 1 is a longitudinal sectional elevation of theimproved device applied to a railwaycar-axle bearing. Fig. 2 is atransverse section on the line 2 2 ol' Fig. l. Fig. 3 is a transversesection ot the improved device on the line 3 3 of F ig. 1. Fig. a is adetached perspective view, enlarged, et' the improved device. Fig. 5 isa sectional detail illustrating the construction when applied toaxle-bearings not having end flanges.

The improved device comprises a hollow casing 10, having at one end areservoir 11 for a supply ot' lubricatingl material and communicating byports 12 13 at the sides with the interior of the casing. The upperVtace let of the casing 10 is concaved in general conformity to theaxle-bearing represented at 15, but ot' greater radius, and disposed inthis con caved portion are spaced longitudinal ribs 16 17, the ribsconnected at the ends by transverse ribs 18 lil, curved to corresijiomlto the liearing. The longitudinal ribs 16 17 are also curvedtransversely in conformity with the bearing, so that the latter bearsuniformly upon all the ribs. F led-apertures 2O connect the interior olithe casing lll with the area within the ribs 16 17 18 1), so that thelubricant will 'flow therethrough, as will be obvious.

liletween the casing 10aud the adjacent 'face ot the axlesbox 21 aresprings 92 233, operating to hold the casing y ieldabl yin engagementwith the bearing and secured by a keeper 2&1.

llt/'hen the device is applied to a bearing having an end flange 25, asin Figs. 1 and 2, a well 26 is Yformed in the casing to receive thesame, as shown; but when applied to bearings not having end [langes thewell portion will not be required, as illustrated in liig. 5.

ft. feed-aperture 2T is formed in the reservoir 1l, through which thelubricant is introduced by means ot any suitable spout inserted throughthe usual detachable cap member 2510i" the axle-box. By this simpleconstrue tion with the reservoir 1l lilled with lubricating material,such as the grade of oil usually employed for axle-bearings, the samewill ilow by gravity through the ports 12 153 and thence up into areadelined by the ribs 16, 17, 18, and. 19 and against the bearing. As thebearing rotates a limited amount ot' the lubricant is carried upward andbeneath the bearing member 29; but only a sul'licient amount of thelubricant will be thus carried to properly lubricate the bearing,leaving the surplus in the cavity within the ribs. .lhus ne waste ot thelubricant occurs, and any small surplus which may be carried past theribs 16 or 17, as the case may be, will run back into the portion of theconcave recess in the member 10 and be there retained and not ilow overthe sides olf the same.

lhe device will operate with equal el'liciency without regard to thedirection elI motion oi the journal.

'lhe head oi oil in the reservoir 11 will insure the constant anduniform supply to the distributing recess or cavity within thebearing-ribs, as will be obvious.

Having thus described the invention, what is claimed 1. .ln a device otthe class described, a casing having a comn'iunicatinglubricant-reservoir at one end extending above the saine and with aconvex upper surface havingl longitudinal |)cz'1,ring-ribs spaced apartand connected at by transverse bearing-ribs curved to conform to saidjournal and bearing beneath the same, said Casing having feed-apertureswithin the area defined by said ribs.

In testimony that I elarn the foregoing' as my own I have hereto aXed mysignature in the presence of two witnesses.

ALONZO H. LAYTON.
